We claim: 7

1. A bearing liner comprising: a bearing metal body having a bore for reception of lubricant and a plurality of grooves parallel with the bearing axis and closed at their ends, one of said grooves midway between the edges of the liner in communication at its longitudinally central portion with said bore, a second ofsaidgrooves spaced from said. bore communicating groove counter to the direction of revolution of the ournal, a relatively shallow groove extending diagonally from the end of the central groove adjacent the hub plate contacting end of the liner to the opposite end of the spaced groove and a relatively shallow groove extending from the end of the spaced groove adjacent the hub plate contacting end of the liner to said end to lubricate the hub plate. v a

2. A bearing liner comprising: a bearing metal body having a bore for reception of lubricant and a plurality of grooves parallel with the bearingaxis and closed at their ends, one of said grooves midway between the edges of the linerin communication at its longitudinally central portion with said bore, a second of said grooves spaced from said bore communicating groove counter to the direction of revolution of the journal, and a. relatively s iallow groove extending diagonally from an end of the central groove to the opposite end of the spaced groove.

3. Abrass for locomotive bearings comprising, in combination: a semi-cylindrical bearing body; a longitudinal groove in the bearing surface of said body adjacent the back edge thereof;-the side of said groove toward said back edge meeting the bearing surface of the body at an abrupt angle to seal said side of the groove by coaction with a journal surface; the remaining side of the groove meeting the bearing surface at an acute angle opening toward the groove; and means to feed lubricant under pressure to said groove.
